1、 Overview of Generator Noise Control Equipment:
The noise control project of the generator room adopts the principle of treating both symptoms and root causes. It designs and constructs noise reduction, sound absorption, shock absorption, and sound insulation from the entrance and exit of the generator room, the diesel engine inlet system, the water tank cooling and exhaust system, and the exhaust system of the waste smoke pipe. It effectively comprehensively controls the various ways in which the noise from the diesel generator room spreads outward, limits the noise inside the generator room, and divides and breaks down the noise to be discharged outside the generator room, comprehensively eliminating it. According to user requirements, sound absorption and insulation measures can be taken on the ceiling and walls of the computer room to reduce noise inside the room. To ensure that the room temperature and diesel engine operating temperature do not rise, forced ventilation and exhaust measures are taken. Timely supplement the fresh air required for the operation of the generator, and exhaust the polluted and hot air in a timely manner. Install sound-absorbing panels, sound-absorbing sheets, and shock-absorbing sheets in the intake and exhaust ducts. The installation of a secondary muffler on the exhaust pipe has received unanimous praise from users for its technical content, noise reduction effect, and professional level over the years.

When the generator is generating electricity normally, the noise will reach 106dB (A) or above. If not treated properly, it will have a certain impact on the surrounding environment. According to the propagation path of noise, the generator room needs to adopt control technologies such as sound absorption, sound insulation, noise reduction, vibration isolation, and damping. The specific measures for noise control in the generator room include:
① Silencing in the exhaust duct of the generator: Install a two-stage damping muffler on the exhaust duct of the generator to reduce noise;
② Sound insulation at the exhaust outlet of the generator: Install an air outlet silencing groove at the exhaust outlet of the generator; When the diesel engine is working, it generates a large amount of heat, which needs to be extracted (discharged) from the engine room to ensure that the temperature in the engine room does not exceed 50 degrees, providing a normal working environment for the generator set.
③ Sound absorption at the inlet of the generator: Install a powered air inlet silencing groove above the rear of the generator in the machine room; Each generator set requires a large amount of fresh air during operation, mainly used for diesel engine combustion and generator cooling.
④ Overall sound insulation in the computer room: Install soundproof doors on the doors of the generator room and install sound-absorbing materials on the walls.

2、 Scope of application: Suitable for noise control in imported Cummins, Rolls Royce, Mitsubishi, Caterpillar and various types of domestic generator rooms.
